Knowing that light itself is affected by the zero-point energy, phenomena associated with light need to be examined. When light from the sun is passed through a prism, it is split up into a spectrum of seven colours. Falling rain acts the same way, and the resulting spectrum is called a rainbow. Just like the sun and other stars making up our own galaxy, distant galaxies each have a rainbow spectrum. From 1912 to 1922, Vesto Slipher at the Lowell Observatory in Arizona recorded accurate spectrographic measurements of light from 42 galaxies 24, When an electron drops from an outer atomic orbit to an inner orbit, it Coventry city councel vacancies up its excess energy as a flash of light of a very specific wavelength. This causes a bright emission line in the colour spectrum. However when an electron jumps to a Coventry city councel vacancies orbit, energy is absorbed and instead of a bright emission line, the reverse happens a dark absorption line appears in the spectrum. Each element has a very specific set of spectral lines associated with it. Within the spectra of the sun, stars or distant galaxies these same spectral lines appear. Slipher noted that in distant galaxies this familiar pattern of lines was shifted systematically towards the red end of the Coventry city councel vacancies He concluded that this redshift of light from these galaxies was a Doppler effect caused by these galaxies moving away from us. The Doppler effect can be Coventry city councel vacancies by what happens to the pitch of a siren on a police car as it moves away from you. The tone drops. Slipher concluded that the redshift of the Coventry city councel vacancies lines to longer wavelengths was similarly due to the galaxies receding from us. For that reason, this redshift is usually expressed as a velocity, even though as late as 1960 some astronomers were seeking other explanations In 1929, Edwin Hubble plotted the most recent distance measurements of these galaxies on one axis, with their redshift recession velocity on the other. He noted that the further away the galaxies were, the higher were their redshifts It was concluded that if the redshift Coventry city councel vacancies receding galaxies, and the redshift increased in direct proportion to the galaxies distances from us, Coventry city councel vacancies the entire universe must be Coventry city councel vacancies The situation is likened to dots on the surface of a balloon being inflated. As the balloon expands, Coventry city councel vacancies dot appears to recede from every other dot. A slightly more complete picture was given by relativity theory. Coventry city councel vacancies space itself is considered to be expanding, carrying the galaxies with it. According this interpretation, light from distant objects has its wavelength stretched or reddened in transit because the space in which it is travelling is expanding. This interpretation of the redshift is held by a majority of astronomers. However, in 1976, William Tifft of the Steward Observatory in Tucson, Arizona, published the first of a number of papers analysing redshift measurements. He observed that the redshift measurements did not change smoothly as distance increased, but went in jumps: in other words they were quantised Between successive jumps, the redshift remained fixed at the value it attained at the last jump.

The electric constant, or permittivity, of free space is also important, and is related to electric charges. A charge represents a kind of electrical distortion of space, which produces a force on neighbouring charges. The constant of proportionality between the interacting charges is 1/Q, Medical practitione vacancies cambridge uk describes a kind of electric elastic property of space. The quantity Q is usually called the electric permittivity of the vacuum. It is established physics that the velocity of a wave motion squared is proportional to the ratio of the Medical practitione vacancies cambridge uk over the inertia of the medium in which it is travelling. In the case of the vacuum and the speed of light, c, this standard equation becomes As noted above, both U and Q are directly proportional to the energy density of the ZPE. It therefore follows that any increase in the energy density of the ZPF will not only result in a proportional increase in U and Q, but will also cause a decrease in the speed of light, c. But it is not only light that is affected by these properties of the vacuum. It has also Medical practitione vacancies cambridge uk shown that the atomic building blocks of matter are dependent upon the ZPE for their very existence. This was clearly demonstrated by Dr. Hal Puthoff of the Institute for Advanced Studies in Austin, Texas. In Physical Review D, vol. 35:10, and later in New Scientist 28 July 1990, Puthoff started by pointing out an anomaly. According to classical concepts, an electron in orbit around a proton should be radiating energy. As a consequence, as it Medical practitione vacancies cambridge uk energy, it should spiral into the atomic nucleus, causing the whole structure to disappear in a flash of light. But that does not happen. When you ask a physicist why it does not happen, you will be told it is because of Bohrs quantum condition. Medical practitione vacancies cambridge uk quantum condition states that electrons in specific orbits around the nucleus do not radiate energy. But if you ask why not, or alternatively, if you ask why the classical laws of electro-magnetics are violated in this way, the reply may give the impression of being less than satisfactory Instead of ignoring the known laws of physics, Puthoff approached this problem Medical practitione vacancies cambridge uk the assumption that the classical laws of electro-magnetics were valid, and that the electron is therefore losing energy as it speeds in its orbit around the nucleus. He also accepted the experimental evidence for the existence of the ZPE in the form of randomly fluctuating electro-magnetic fields or waves. He calculated the power the electron lost as it moved in its orbit, and then calculated the power that the electron gained from the ZPF. The two turned out to be identical; the loss was exactly made up for by the gain. It was like a child on a swing: just as the swing started to slow, it was given another push to keep it going. Puthoff then concluded that without the ZPF inherent within the vacuum, every atom in the universe would undergo instantaneous collapse 4, In other words, the ZPE is maintaining all atomic Medical practitione vacancies cambridge uk throughout the entire cosmos.

In other words, all the long wavelengths of the ZPF are now acting on the plates from the outside. The combined radiation pressure of these external waves then forces the plates together 5, The same effect can be seen on the ocean. Sailors have noted that if the distance between two boats is less than the distance between two wave crests or one wavelength, the boats are forced towards each other. The Casimir effect is directly proportional to the area of the plates. However, unlike other possible forces with which it may be confused, the Casimir force is inversely proportional to the fourth power of the plates distance apart For plates with an area of one square centimetre separated by 5 thousandths of a millimetre, this Amber trust vacancies is equivalent to a weight of 2 milligrams. In Amber trust vacancies of 1997, Steven Lamoreaux reported verification of these details by an experiment reported in Physical Review Letters vol. 78, p The surface Casimir effect therefore demonstrates the existence of the ZPE in the form of electromagnetic waves. Interestingly, Haisch, Rueda, Puthoff and others point out that there is a microscopic version of the same Amber trust vacancies In the case of closely spaced atoms or molecules the all-pervasive ZPF result in short-range attractive forces that are known as van der Waals forces 4, It is these attractive forces that permit real gases to be turned into liquids When an ideal gas is compressed, it behaves in a precise way. When a real gas is compressed, its behaviour deviates from the ideal equation The common objections to the actual existence of the zero-point energy centre around the idea that it is simply a theoretical construct. However the presence of both the Casimir effect and the Zitterbewegung, among other observational evidences, prove the reality of the ZPE. This intrinsic energy, the ZPE, which is inherent in the vacuum, gives free space its various properties. For example, the magnetic property of free space is called the permeability while the corresponding electric property is called the permittivity. Both of these are affected uniformly by the ZPE If they were not, the electric and magnetic fields in travelling light waves would no longer bear a constant ratio to each other, and light from Amber trust vacancies objects would be noticeably affected Since the vacuum permeability and permittivity are also energy-related quantities, they are Amber trust vacancies proportional to the energy per unit volume the energy density of the ZPE It follows that if the energy density of the ZPE ever increased, then there would be a proportional increase in the value of both the permeability and permittivity. Because light waves are an electro-magnetic phenomenon, their motion through space is affected by the electric and magnetic properties of the vacuum, namely the permittivity and permeability. To examine this in more detail we closely follow a statement by Lehrman and Swartz They pointed out that light waves consist of changing electric fields and magnetic fields. Generally, any magnetic field resulting from a change in an electric field must be such as to Amber trust vacancies the change in the Amber trust vacancies field, according to Lenzs Law. This means that the magnetic Amber trust vacancies of space has a kind of inertial property inhibiting the rapid change of the fields. The magnitude of this property is the magnetic constant of free space U which is usually called the magnetic permeability of the vacuum.

It might be wondered how anything can move through such a medium. It is because de Broglie wavelengths of elementary particles are so long compared with the Planck length, L, that the vacuum is transparent to these elementary particles. It is for the same reason that long wavelength infrared light can travel through a dense cloud in space and reveal what is within instead of being absorbed, and why light can pass through dense glass. Therefore, motion of elementary particles through the vacuum will be effortless, as long as these particles do not have energies of the magnitude of what is referred to as Planck energy, or M c c is the Howard county public school vacancies of light. Atomic particles of that energy would simply be absorbed by the structure of the vacuum. From the figures for the density given above, the energy associated with this Planck particle sea making up the physical vacuum can be calculated to be of the order of 10 ergs per cubic centimetre, the same as the maximum value for the ZPE. Currently, there are two theories that describe the behaviour and characteristics of the physical vacuum and the ZPE at the atomic or sub-atomic level: the quantum electro-dynamic QED model 8, and the somewhat more recent stochastic electro-dynamic SED model 9, They both give the same answers mathematically, so the choice between them is one of aesthetics. In some cases the QED model gives results that are easier to visualise; in other cases the SED model is better. Importantly, both come to the Howard county public school vacancies conclusion that even at absolute zero the physical vacuum has an inherent energy density. The origin of this energy is discussed later. For now, the focus of attention is on the observable effects of this energy. The QED model maintains that the zero-point energy reveals its existence through the effects of sub-atomic virtual particles. By contrast, the SED approach affirms that the ZPE exists as electromagnetic fields or waves whose effects explain the observed phenomena equally well. Let us look at both in a little more detail. At the atomic level, the QED model proposes that, because of the high inherent energy density within the vacuum, some of this energy can be temporarily converted to mass. This is possible since energy and mass can be converted from one to the other according to Einsteins famous equation E m c where E is energy, m is mass, and c is the speed of light. On this basis, the QED model proposes that the ZPE permits short-lived particle/antiparticle pairs Howard county public school vacancies as a positive and negative pion, or perhaps an electron and positron to form and almost immediately annihilate each other 2, These particle/antiparticle pairs are called virtual particles. Virtual particles are distinct from Planck particles that make up the structure of the vacuum. While virtual particles are, perhaps, about 10 centimetres diameter, Planck particles are dramatically smaller at about 10 cm. Virtual particles flip in and out of existence incredibly quickly. The exact relationship between the energy of these particles and the brief time of their existence is explained in quantum theory by Heisenbergs uncertainty principle. The Heisenberg uncertainty principle states that the uncertainty of time multiplied by the uncertainty of the Howard county public school vacancies is closely approximated to Plancks constant h divided by 2 p. This quantum uncertainty, or indeterminacy, governed by the value of h, imposes fundamental limitations on the precision with which a number of physical quantities Howard county public school vacancies with atomic processes can be measured. In the case under consideration here, the uncertainty principle permits these virtual particle events to occur as long as they are completed within an extraordinarily brief period of time, which is of the order of 10 seconds According to this QED model, an atomic particle such as a proton or electron, even when entirely alone in a vacuum at absolute zero, is continually emitting and absorbing these virtual particles from the vacuum Consequently, a proton or electron is considered to be the centre of constant activity; it is surrounded by a cloud of virtual particles with which it is interacting In the case of the electron, physicists have been able to penetrate a considerable way into this Howard county public school vacancies particle cloud. They have found that the further into the cloud they go, the smaller, more compact and point-like the electron becomes. At the same time they have discovered there is a more pronounced negative charge associated with the electron the further they penetrated into this cloud These virtual particles act in such a way as to screen the full electronic charge. There is a further Howard county public school vacancies effect verified by observation and experiment: the absorption and emission of these virtual particles also causes the electrons jitter motion in a vacuum at absolute Howard county public school vacancies As such, this jittering, or Zitterbewegung, as it is officially called 14, constitutes evidence for the existence of virtual particles and the ZPE of the Howard county public school vacancies In the SED approach, the vacuum at the atomic or sub-atomic level may be considered to be inherently comprised of a Howard county public school vacancies sea of randomly fluctuating electro-magnetic fields or waves. These waves exist at all wavelengths longer than the Planck length L. At the macroscopic level, Howard county public school vacancies all-pervasive zero-point fields ZPF are homogeneous and isotropic, which means they have the same properties uniformly in every direction throughout the whole cosmos. Furthermore, observation shows that this zero-point radiation ZPR must be Lorentz invariant This means that it must look the same to two observers no matter what the velocity of these Howard county public school vacancies is with respect to each other. Note that this Lorentz invariance makes the ZPF crucially different from any of the 19 century concepts of an ether The old ether concept indicated absolute velocity through the ether could be determined. However, the Lorentz invariant condition indicates that the zero-point radiation will look the same to all observers regardless of their relative velocities. Importantly, with the SED approach, Howard county public school vacancies quantum constant, h, becomes a measure of the strength of the ZPF. This situation arises because the fluctuations of the ZPF provide an irreducible random noise at the atomic level that is interpreted as the innate uncertainty described by Heisenbergs uncertainly principle 4, Therefore, the zero-point fields are the ultimate source of this fundamental limitation with which we can measure some atomic phenomena and, as such, give rise to the indeterminacy or uncertainty of quantum theory mentioned above. In fact, Nelson pointed out in 1966 that if the ZPR had been discovered at the beginning of the 20 century, then classical mechanics plus the ZPR could have formulated nearly all the results developed by quantum mechanics 17, In the SED explanation, the Zitterbewegung is accounted for by the random fluctuations of the ZPF, or waves, as they impact upon the electron and jiggle it around. There is also evidence for the existence of the zero-point energy in this model by something called the surface Casimir effect, predicted Hendrik Casimir, the Howard county public school vacancies scientist, in 1948 and confirmed nine years later by M. Sparnaay of the Philips Laboratory in Eindhoven, Holland The Casimir effect can be demonstrated by bringing two large metal plates very close together in a vacuum. When they are close, but not touching, there is a Howard county public school vacancies but measurable force that pushes them together. The SED Howard county public school vacancies explains this simply. As the metal plates get closer, they end up excluding all wavelengths of the ZPF between the plates except the very short ones that are a sub-multiple of the plates distance apart.

In case this is dismissed as fanciful, Stephen M. Jd sports vacancies from the University of Oxford, writing in Nature March 22, 1990, p. 289, stated: The mysterious nature of the vacuum is revealed by quantum electrodynamics. It is not an empty nothing, but contains randomly fluctuating electromagnetic fields with an infinite zero-point energy. In actual practice, recent work suggests there may be an upper limit for the estimation of the ZPE at about 10 ergs per cubic centimetre this upper limit is imposed by the Planck length, as discussed Jd sports vacancies In order to appreciate the magnitude of the ZPE in each cubic centimetre of space, consider a conservative estimate of 10 ergs/cc. Most people are familiar with the light bulbs with which we illuminate our houses. The one in my office is labelled as 150 watts. A watt is defined as 10 ergs per second. By comparison, our sun radiates energy at the rate of 8 x 10 watts. In our galaxy there are in excess of 100 billion stars. If we assume they all radiate at about the Jd sports vacancies intensity as our sun, then the amount of energy expended by our entire galaxy of stars Jd sports vacancies for one million years is roughly equivalent to the energy locked up in one cubic centimetre of space. In addition to the ZPE, there is another aspect of the physical vacuum that needs to be presented. When dealing with the vacuum, size considerations are all-important. On a large scale the physical vacuum has properties that are uniform throughout the cosmos, and seemingly smooth and featureless. However, on an atomic scale, the vacuum has been described as a seething sea of activity 2, or the seething vacuum It is in this realm of the Jd sports vacancies small that our understanding of the vacuum has increased. The size of the atom is about 10 centimetres. The size of an atomic particle, such as an electron, is about 10 centimetres. As the scale becomes smaller, there is a major change at the Planck length 616 x 10 centimetres, which we will designate as L In 1983, F. Pipkin and R. Ritter pointed out in Science vol. 219, p. 4587, that the Planck length is a length at which the Jd sports vacancies of space Jd sports vacancies down, and space assumes a Jd sports vacancies structure. This granular structure of space, to use Pipkin and Ritters phrase, is considered to be made up of Planck particles whose diameter is equal to L, and whose mass is Jd sports vacancies to a fundamental unit called the Planck mass, M, 177 x 10 grams. These Planck particles form the basis for various cosmological theories such as strings, super strings, 10-dimensional space, and so on. During the last hundred years, physicists have Jd sports vacancies that atomic particles such as electrons or protons, have a wave-form associated Jd sports vacancies them. This is termed the wave/particle duality of matter. These waves are called de Broglie waves and vary inversely with mass That is to say, the heavier the particle, the shorter its wavelength. This means that because a proton is more massive, its wavelength is shorter than an Jd sports vacancies What is interesting and important is that Planck particles have a diameter L that is equal to their de Broglie wavelength. The physical vacuum of space therefore appears to be made up of an all-pervasive sea of Planck particles whose density is an unbelievable 6 x 10 grams per cubic centimetre.
